Once in a while, it is time to bethink the beginning. Just like we celebrate our birthdays, we can pay tribute to the cradle of photography, the camera obscura. As photography is not a spring chicken anymore, the party starts off slow: in the form of the Pinhole Day which is taking place for the 13th time today. Everybody who is interested in pinholes and long exposures is cordially invited to join the celebration. The only condition for the participation is a pinhole camera, no matter whether it is analogue, digital, self-built or bought.
